The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said that the temperature index - the "feeling hot" level - has reached the dangerous threshold of 50 degrees Celsius in Los Baños, Laguna for 2 consecutive days this week.
PAGASA's weather forecast shows that at least 17 other areas are also warned of dangerous heat waves, with the capital Manila recording a temperature of 42 degrees Celsius. With this temperature, the risk of cramps, exhaustion or even stroke due to the sun is entirely possible if exposed for a long time outdoors.

The same situation is also happening in India and Pakistan, where temperatures have surpassed 44 degrees Celsius nearly a month earlier than usual, according to CNN.
According to the Pakistan Meteorological Agency, Balochistan recorded temperatures of up to 49 degrees Celsius this week - equivalent to the summer temperature in the Death Valley (US), the hottest place in North America.
The sun came too fast and too fiercely, said Ayoub Khosa, a recent Balochist. "The power outage lasts up to 16 hours/day, making it impossible for people to escape the sun".
In India, authorities have warned that April will have above-average hot days. New Delhi, home to more than 16 million people, has seen three days of heat above 40 degrees Celsius in the month alone. Temperature in Rajasthan has reached 44 degrees Celsius, forcing workers and farmers to work in unbearable conditions.
Children and women are the hardest hit, said ba ba ba ba Sunitoni, a representative of a womens organization in Rajasthan. "It is normal for people going out to the fields without water to drink, to be dizzy, nauseous and faint."
Not only human health, the crop is also severely affected. Unusual high temperatures cause crops to lose water, lose flowers, reduce productivity and be susceptible to pests and diseases. "We lost the whole crop and our income. But there is nowhere else to go" - Balu Lal farmer lamented.
In Thailand, the country's Meteorological Department also forecasts that the North, Northeast and Central regions will face temperatures of up to 39 degrees Celsius with local thunderstorms. Southern provinces are warned to be on guard against thunderstorms and large waves over 2m high in the Gulf of Thailand and the Andaman Sea.
The Vietnam National Center for Hydro-Meteorological Forecasting said that from April 19, provinces from Thanh Hoa to Phu Yen will start recording widespread heat, with the highest temperature commonly from 35-37 degrees Celsius, some places exceeding 37 degrees Celsius.
From April 21, the hot weather will spread to the entire Northern region (including Hanoi) and the Southern provinces. The highest temperature forecast for the day in the North (including Hanoi): 35-36 degrees Celsius, some places above 37 degrees Celsius. Central region: 36-38 degrees Celsius, the highest place may be above 39 degrees Celsius. Southern region: 35-37 degrees Celsius.
The hot weather in the North may last until 22/4; the Central region is likely to last until 23/4; the South may continue to have hot weather for many days.
